The muscles attach to strong tendons, which either attach to or directly connect with the bones. it is the ability of smooth muscle to be stretched then relax maintaining constant pressure 1) If the smooth muscle is quickly stretched, it contracts. The signal, an impulse called an action potential, travels through a type of nerve cell called a motor neuron. agents released from nerves locally or by circulation, Smooth muslce has slower contraction when compared to skeletal muscle b/c, of unique isoforms of myosin & contractile-related proteins & their distinct regulation, variability of the tension it exerts @ given length, impossible to correlate length & develop tension accurately; no resting length can be assigned, edocrine, paracrine, local nervous system, & autonomic nervous system regulation, 1. increase in cytosolic Ca@+ initiates contraction 2. During anaerobic exercise, the muscles contract intensely at a level nearer to their maximum strength. Single-unit smooth muscle (commonly called visceral muscle) is found on the walls of hollow organs in the digestive tract, urinary tract, and reproductive system. Each type of muscle plays a different role in helping the body move and function properly. The actin filaments (red lines) in smooth muscle run from one side of the cell to the other, connecting at dense bodies and at the cell membrane. All rights reserved.

Investigate the bio-based company that occur for animal lived to exist by various levels of organization: from membranes through to organelles, cells, journals, organ systems, and to the entirely animal. When the bands in the sarcomeres relax or contract, the whole muscle extends or relaxes. The main fuel sources are ATP or glucose, and the body uses less oxygen, fat, and protein. Pick up the cellular 3D models and examine the nuclei, myofibrils, mitochondria and more to understand how the intracellular components enable each muscle cell to perform the functions characteristic for that muscle tissue. This type of muscle contraction is controlled not by the central nervous system in the brain but by the autonomic nervous system, the portion of the peripheral nervous system that coordinates involuntary actions like breathing and heart rate.
